Boot manager problem with triple boot XP/Vista/Win7

On my system I could dual boot with EasyBCD into XP Pro and Vista Ultimate.
Now I wanted to add Windows 7 RC64bit  to my system. I booted into XP, installed Partition Magic 8, made room on the far right end of my hard disk, made that partition bootable and set it to active(so fist 2 partitions are XP and Vista, then 2 partitions contain data and last partition is for Win7).
I was able to install Win7 with no problem.
Question: I want the boot manager to show XP, Vista and Win7. How? I need to able to delete Win7 (because I use RC version)
Problem: after installing win7 I didn't get the boot manager. Bcdedit shows only Win7. If I set the Vista partition to active I get the error: "windows failed to start" and "repair your computer" and "File: \BOOT\BCD
Status: 0xc000000F
Info: An error occurred while attempting to read the boot configuration data"
When I set the XP partition to active I get my old boot manager with XP and Vista. I can boot into XP without a problem. If I boot into Vista I get the error: autochk program not found and then a BSoD with: Stop C000021a and 0xc000003a

I am one step further. I made the Vista partition active and booted from the Vista setup disk. Then I chose Repair your computer. Now I have a boot manager with Vista and Win7.
1. How can I add XP to this
2. How can I see XP and Win7 to the explorer? Disk Management in Vista doesn't allow me to assign drive letters to these partitions.

I know what I did wrong: I shouldn't have made the Win7 partition active.
Now I set the Vista partition to active (where EasyBCD is installed). I deleted the Win7 partition and reinstalled win7. I can now boot into Vista and Win7.
The only problem remaining is that if I choose XP from the boot loader, XP starts up, but then I get an boot.ini error,followed by a BSoD

What is the contents of your boot.ini file?  It may be referencing the wrong partition.  Here is a good article about the boot.ini file:

I do not know what the content is. I can't reach XP, nor from Vista, neither from Win7.
Is there a way to look at it while booting XP (before it gives me a BSoD)?

I waited a long time to try this, because I really couldn't loose my Vista partition. Now I had the time and it worked. Thanks!
